KELLEY D. EVAN S, 01 HAMILTON, OHIO, ASSIGNOR OF ONE-HALF TO 0. E.HOOVER, OF

HAMILTON, OHIO AUTOMATIC TYPEWRITER Application filed June 12,

' This invention relates to automatic typewriters and particularly tothat type of au tomatic typewriters controlled by a record sheet orstrip having perforations which select the keys to be actuated andpermit suitable parts or members connected with the key levers of thekeyboard to be moved into the path of a motor driven actuator whichdepresses the keys and actuates the type bars.

The present invention embodies numerous improvements in the general typeof machines specified above, one of the objects of the invention beingto avoid the actuation of the keys during the normal operation of themachine when controlled by the perforated record sheet.

A further object is to provide eificientand practical means whereby themotor driven actuator causes the operation of the type bars whether theselection occurs through the perforated record sheet or by the manualdepression of the keys corresponding to such type bars. In other wordsit is one of the objects to provide a typewriter of the auto matic typewherein the type bars are brought into operative relationship with theactuator whether through the medium of the record sheet or through theactuation of the keys, so that in both instances the type bars will beactuated by a motor driven part, and in both instances the printedimpressions will be exactly the same in appearance, thus making itpossible for the operator to stop the feed of the record sheet at anypoint and to insert in the communication being written matter notcovered by the record sheet without changing to the slightest degreethe'appearance of the typewritten matter.

The above and other objects are attained by my invention which may behere briefly summarized as consisting, in certain novel details ofconstruction and combinations and arrangements of parts which will bede- 1 scribed in the specification and set forth in the appended claims.

In the accompanying sheets of drawings wherein I have shown anembodiment of my invention which operates very eifective 9 1y, Fig.-1 isa rear view of my improved 1926. Serial No. 115,659. I

Referring now to the drawings, my improved typewriter includes a frame10 at the front of which is a keyboard corresponding to the keyboard ofan ordinary typewriter, a few of the key levers being illustrated at 11.These key levers are pivoted on a crossrod 12 supported by frame 10 andswing in the slots of a comb 18. Each key lever has a downward extension14 terminating in a forwardly projecting part 15, the downward extensionhaving connected to it a spring 16 connected to a spring bar 17extending across the front part of the frame 10, the

fulcrum wire 19 (Fig. 10) mounted in the customary slotted segment 20,and when the type bar is swung to printing position itv enters the usualguide indicated 'at 21. have indicated the platen conventionally at 22,but have-not illustrated the carriage which supports the platen as thismay be of suitable or usual form. However, portions of the carriageframe are illustrated at 22*- and this frame will be referredto later.

It will be observed that there is no direct connection between thekeylevers and the type bars. is connected by a pin and slot connectionwith a sub-link 23, the sub-links for all the different type; bars beingfulcrumed on a wire or rod 24 (Fig. 3) extending transversely across themachine in a slot of a forwardly facing comb-25. Each sub-link has aforwardly and upwardly inclined slotted portion 26 engaged by a pin 27of an actuating .member 28, heretofore termed the actuating lever, oneof which is provided for each of the different key levers'of thekeyboard. i

The different; actuating levers 28 are arranged side by side and arespaced apart by the teeth of front and rear combs 29 and 30 (Fig. 3),and all of these'actuating levers are independently capable of a slightsliding movement to bring them into the path -of the motor drivenactuator (53 to be described later), and of a rocking movement to shiftthe sub-links 23 which in turn actuate the type bars 18 as explainedabove.

The rocking movement of the actuating levers 28 occurs about astationary fulcrum shaft or bar 31, which extends across the frame ofthe machine and which engages in slots 32 on the lower sides of theactuating levers. The latter are supported by the fulcrum shaft 31 andby a cross-bar 33-forming a part of comb 30, and they are normally heldin the position illustrated in Fig.3, at which'time the rear portions ofthe actuating levers rest on the cross-bar'33, by springs 34 connectedto the upper rear portions of the actuating levers and to a rearspring-bar 35.

At the upper forward part of each'a'ctuating lever is an extension 36which, when the actuating lever is in the position illustrated in Fig.3, is normally out of the path of the motor driven actuator, but whichwhen the actuating lever is slid forwardly bar to printing position.

On the other hand each type bar either through the selection by therecord sheet or by depression of the corresponding key lever, comes intothe path of the actuator and is rocked to the position shown in Fig. 6so as to swing the corresponding type A d lit-ion al ly, the actuatinglever is'pro vided at its rear end with a spring actuated pin 37, whichas will be explained, is normally held in upper or, retracted positionby the unporforatod part of the record shoot but is permitted to belowered by a pin spring 38 (Fig. 4) when a perforation of the recordsheet comes under the pin, Similarly the front end of the actuatinglever has a spring actuated pin 39 which is normally held. rctractcdbythe for ward extension 15 of the corresponding key lever 11, but thispin is adapted to be moved upwardly under the action of the pin spring40 (Fig. 6) when the key lever is depressed bringing a slot 41 oppositethe pin 39 (Fig. 7). i i

The perforated record sheet which I ropose to employ in my improved macine,

may be exactly similar to those which have been used for a great manyyears on the socalled Hooven Automatic Typewriters, a record sheet ofthis gei'icral type being illus tratcd conventionally in Pillings PatentNo. 1,175,986 and it may be lormed or produced by a perforating machinesuch as illustrated in the Pillings patent above Inentionedor in thehIcCall Patents No. 1,048,560 and No. 1,083,290. This perforated sheetis generally endless and is provided along its margins with perforationsadapted tobc engaged by the teeth of the feeding sprockets, and betweenthe sprocket perforations the sheet is provided with actuatingperforations which in this instance when they come beneath the springpins 37 permit the latter to drop into them so that the actuating levers28 will be shifted in the manner hereinafter more fully explained.

In Figs. 3 and 4 of the drawings the record sheet is indicated at 42,this shcet being adapted to travel over a shie d 43 which extends acrossthe lower rear part of the machine, as illustrated in the drawings.

This shield is preferably formed of two pieces of properly shaped sheetmetal and its upper part is cylindrical, there being between the picccsforming theshicld a slot -14 which extends the full length of the shieldand is directly beneath the rear pins 37 of lever will be movedforwardly.

oscillating bar, the corresponding actuating The bar 45 is supported ona shaft 46 extending centrally through the upper part of the shield andsupported in the side members of 'the frame 10. .Fixed to this shaft aresprocket wheels 47 which feed the perforated record sheet-42,.one of thesprocket wheels being rovided with a ratchet wheel 48 adapt. to beoperated by a pawl 49 (Fig.

.3 hereinafter described so that the record sheetwill be given astep-by-step movement.

It might'be here stated that one end of shaft 46 is journalled in one ofthe side members-of frame'lO, as indicated in Fig. 2, but the otherendis journalled in an upstanding supporting arm 46 which is in theplane of the opposite side of frame 10,,this arm being at the free endof a horizontal arm 46 extending across beneath shaft-46 from the firstmentioned side of frame 10, as indicated in Fig. 4. The free end of arm46 and of the upright supporting arm 46 'lie in r a slot or opening 46extending up from the bottom of-the adjacent side of frame 10, asindicated in Figs. 2,4 and 8. This forms virtually an open-ended supportfor shaft 46 and its associated parts, making it possible to slip anendless record sheet inwardly from the side having opening 46 oversprockets 47' and shield 43. i

. The rear oscillating bar 45 which is adapted to'engage the rear springpins 37 is one of two simultaneously moving oscillating bars, the otherbeingillustrated at 50, this oscillating bar being adapted to engage thefront spring pins 39 of the actuating levers 28 when the latter aremoved up- I wardly through the slots 41 of the key lever extensions 15when the key levels are depressed so that this front oscillating bar maymove the actuating levers forwardly by engaging the front spring pins 39in the same manner that the rear oscillating bar 45 may move theactuating levers by engaging the rear spring pins 37. This bar issupported by arms 51 secured to a rock shaft 52 which extends across thelower front ortion of the machine; and is journalled in the sides of theframe'lO.

It 'was heretofore explained that when an actuating lever 28 is movedforwardly the frontupward extension 36 is moved into" the path. of'amotor driven actuator so as to rock the actuating levers about thefulcrum shaft" 31 and thus swing the type bars to printing position, itbeing understood that when the actuating levers 28 are in their normalrear positions they are not engaged by the actuator. This actuator is inthe form of a bar 53 which extends across the upper front part of themachine and is supported by two arms 54 secured to a rock shaft 55 whichextends across the machine and is journalled in the sides of the frame10.

' The bars 45 and 50 which move the actuating levers 28 forwardly havesubstantially a horizontal oscillatory motion, while the motor drivenactuator 53 which rocks the actuating levers 28 has a substantiallyvertical oscillatory motion.

The main drive shaft of the machine is shown at 56. This shaft isrotated by a motor which may be located at any suitable point but inthis instance is shown conventionally at 57 and as illustrated issupported inside the frame 10 and has a shaft 58 connected to .the shaft56 by spiral gears 59 or other suitable form of speed reducing ears.

This shaft 56 which rotatesv continuously as long as the machine is inoperation, is provided near one end with two eccentrics 60 and 61 (Figs.3 and 9) which are secured to the shaft in fixed relation to each other,

.one being preferably 90 in advance of the One of. these eccentricsactuates the two horizontally oscillating bars 45 and 50 other.

rock shaft 52, whichactuates the front oscillating bar 50.

The arm 62 carries the pawl 49 which engages one of the sprockets, 48which are secured to a shaft 46 and which actuate the record sheet.During normal operation on each rear-stroke of arm 62 the twooscillating bars 45 and 5() swing forwardly and coincidentally therecord sheet is moved forwardly one step. 3 However, it is generally thecase that when the typewriting is done 1 through the actuation of thekey levers 11,

it is desired .that the record sheet be stationary and accordinglyprovision is made for rendering inoperative the pawl and ratchetmechanism which \feeds the record sheet. This is accomplished in thisinstance, by a short bell-crank lever 67 3) which when rockedfrom normalposition is adapted to'move the pawl 49 downwardly so as to be clear ofthe teeth of ratchet 49.

This bell-crank lever may be operated in any suitable manner as by a rod68 which may extend forwardly to the front of the machine where it maybe shifted by a key or other means within the convenient reach of theoperator. It will be understood, of course, that by disengaging the pawl49 from the ratchet 48 while the feed of the record sheet is stopped,the remaining parts of the machine continue to operate, this beingessential-because of the fact that with ardly into the path of theoscillating bar of the arrangement of the eccentrics 60 and 61 asdescribed, the actuator 53 is swung downwardly immediately after thebars 45 and 50 are swung forwardly so that in the event a perforation ofthe record sheet has permitted the rear spring pin 37 of any particularactuating lever 28 to move down- .45, or in the event a key lever 11 hasbeen depressed so as to' permitthe front spring pin 39 of thecorresponding actuating lever 2 28 to spring upwardly in front of thefront oscillating bar 50, the actuating lever is first moved forwardlyfrom the position shown in Figs.' 3 and 4 to the position shown in Fig.5, so that the upward extension' 36 of the actuating lever is in thepath of the actuator 53, and then the actuator engages said extension ofthe actuating lever swinging the latter to the position shown in Fig.'6, causing the-type bar' to be swung to printing position, or from theposition shown in Fig. 5 to the position shown in Fig. 6.

As soon as the actuating lever is rocked -to the position stated abovecausing the printing impression to be made, the spring pin 37 or thespring pin 39 as the case may be, is released from the correspondingoscil lating bar 45 or 50, whereupon the actuating lever 28 is restoredto its former position and the extension 36 thereof slidesback frombeneath the engaging lower surface of the actuator 53 by the action ofspring 34:, the type bar coincidently dropping back onto its support.The return of these parts to their normal positions takes place quicklyenough to permit the quick duplication of the'operation even with thesame actuating lever and type bar. 7

It might be here mentioned that the rock shaft 55, to which the actuator53 is attached, is instrumental in the performance of another function,i. e. the step-by-step feeding or spacing of the carriage following eachprinting.impression, and in thls connection it will ,be recalled that inthe early partof the specification it was stated that the feed of thecarriage and the movements thereof.

for tabulations or indentations and for its return, are done positivelythrough motor actuated means,v and this mechanism will now bedescribed." v

The carriage frame 22, portions of which only are shown, (the carriageitself being omitted as it forms 'nopart of the present invention) isslidably mounted on two wayrods and 71. Though the particular gearmembers herein illustrated for imparting the extends inwardly into thespiral groove.

This nut consists of a sleeve having at one end a gear and at its otherend a ratchet wheel 76. This ratchet wheel is adapted to be engaged by apawl 7 6 (Fig. 3) pivotally mounted at the upper end of an'arm 77secured to rock shaft 55 which, as previously explained, is rocked backand forth with the oscillations imparted to the motor driven actuator53. The pawl is pressed upward by a spring 76* shown in Fig. 4. Themanner in which this pawl is'controlledso that it causes the carriage tofeed one step immediately after a printing impression is made will beexplained hereinafter.

The gear 75 is engaged by a gear 78 carried by a sleeve 79 pinned, orotherwise secured to 'a shaft 80 which is motor driven in a manner to beexplained presently. The sleeve is preferably provided with a fairlydeep groove 81 (Fig. 1) to permit the actuation of and to guide the pawl76. This shaft 80 has its outer end mounted in a suitable bearing in oneside of frame 10 and its inner end is journalled-in a frame 82', thebase of which extends down to and is suitably secured to the cross barforming a part of comb 25. At its upper end this frame 82 has a pair ofspaced arms 82 located on opposite sides of the nut'i'et and of the gear78 with its sleeve 79 and forming the inner bearings for shaft 80 andalso serving to hold the nut 7 4 against endwise movement on thespirally grooved shaft 73 of the carriage. It will be observed fromFigs.1 and 3 that the lower portion of the frame 82 is curved over rock shaft55 and that the arm 77 which actuates the pawl 76 extends through a slotin this frame.

The shaft 80 near its outer end is connected by bevel gearing 83 to .adiagonall .disposed shaft 84: provided at its lower en with a bevel gear85 adapted to be en aged by either of two bevel gears 86 and 8 splinedto the main driving shaft 56 and through the medium of which shafts 84and. 80 may be rotated in either direction so as to rotate the nut 7i ineither direction and move the carmove the gears, 86 and.87 into and out.of

. two actuating levers 28f and 28 which are side or the other of disk 92holds the gear similar to the actuating levers 28 associated with theprinting key levers, and are mounted. and have movements or are actuatedin precisely the same way as "the actuating levers associated with theprinting key levers, being selectively controlled either by theperforated record sheet or by the depressing of two shift keys carriedby the key levers forming a part of the regular keyboard equipment.These two actuating levers L8 and '28 differ from the main actuatinglevers 28 in the respect that their forward ends are connected by links91 (Figs. 1 and 9) to the two shifters 89 and 90, the arrangement beingsuch that when either actuating lever 28 or 28 is rocked, thecorresponding bevel gear 86 or 87 is moved into engagement with thebevel gear 85.

The gear 87 is utilized for the carriage return and the gear 86 formoving the carriage for indenting or tabulating purposes.

"Vhen the gear 87 is shifted by the actuating lever 28 into engagementwith the gear 85 in order to return the carriage, it is held in drivingengagement with gear 85 until the carriage is given its full returnmovement. This is accomplished in this instance by providing on the endof the sleeve forming a part of gear 87 a disk 92 (Fig. 9) having itsperiphery beveled in opposite directions and engaged by a so-calledspring point 93 which by engaging one beveled 87 in'either engaged ordisengaged position. The gear 87 isautomatically disengaged when thecarriage is returned to the desired position -by a releasing lever 94which extends up alongside of the frame and has its lower end forked andin engagement with the sleeve carrying gear 87 whileits upper end isbehind the head 95 on the end of rod 71 which is one of the two rods onwhich 3 the carriage frame is supported, and which corresponds .to theso-called typewriter front rod of ordinary typewriters, this rodcarrying an adjustable stop 97 which can be positioned by the usualmeans wherever desired and is adapted to be engaged by a shoulder 98(Figs. 4 and 8) carried by the carriage frame. The rod 71, unlike thecorresponding rod in the usual'typewriter construction, is capable of aslight endwise movement, being normally held in one extreme position bya spring 99 (Figs. 1 and 9) engaging-the head 95. \Vhen the shoulder 98of the carriage engages the adjustable stop 97, the rod 71 is shiftedendwise (against spring 99) sufiiciently to rock lever 94 far enough tocause the disk 92 to pass the spring point, in which event the gear 86is disengaged from the gear 85 and is held in disengaged osition.

The gear 86 used or tabulating or identing purposes is held inengagement with gear 85 until automatically released by the followingmeans: The rear end of the actuating lever 28 which as before explainedshifts the gear: 86 into engagement with gear 85, is provided withanupstanding rod 100 (Figs; 8 and 9) connected to a pin 101 (Fig. 9) ofthe tabulating frame 102 which is adapted to rock back and forth on themain frame .10 of the machine, but unlike the tabulatingframe ofordinary. typewriters, is capable of slight endwise movement on the mainframe. The function of the rod 100 connected to pin 101 of thetabulating frame is to swing it inwardly and when this occurs the frameis held in its inward position by reason of the fact that a pin 103(Figs. 8 and 9) carried by the tabulating frame is by theinward movementcarried slightly above a'locking plate 104, and when the pin passesabove the locking plate the tabulating frame is moved slightly inendwise direction b a spring 105 (Fig. 9) surrounding one o the pivotsfor the frame.. This carries the pin over the locking plate which istherefore held in spring 105) sufficiently far that the pin 103 iscarried past the locking plate 104, in which event the tabulating frameagain swings outward under the action of spring 108 causing gear 86 tobe disengaged from ear 85.

of the record sheet or the manual depression of a carriage shift-keycauses the actuator 53 to rock actuating lever 28 so as to cause gear 86to be moved into engagement with gear 85, and that it will be held IThus it will be seen that a perforation ton.

motor, gear 87 being held in engagement with gear 85 until the carriageis returned oint determined by the position of the a justable stop ofthe front rod' 71 of the main frame which then causes the disengagementof gear 87 from gear 85.

It is tobe understood that normally gear 85 is disengaged from bothgears 86 and 87 and it is only when the tabulating or return ,moves itforward one step, the nut 74: as awhole is rotated through one stepsufficient to space the carriage frame. During this movement of the nutthe gears 7 5,78, shaft 80, gears 83 and shaft 84: with its gear 85,

turn idly.

Inasmuch as the rock shaft 85 is rocked by one of the arms supportingthe actuator 53 and bythe arm 69 actuated by the cocentric on the mainmotor driven shaft 56, it is obviousthat the'pa'wl' 7 6 is given oneforward stroke during each revolution of shaft 56, this stroke occurringimmediately after the type bar has been swungto printing position andduring the return or upward stroke ofthe actuator 53. However, it isdesirable, and in fact necessary, both when the selectionoccurs by theperforated record sheet orbythe manual depression of the key levers,:that the spacing movements be impartedto the ratchet wheel 76 onlyafter printing impressions are made, regardless of the rate theseimpressions are made with respect to the rotation of the motor drivenshaft 56 except for the spacing between words which is taken care of bya third special actuating lever here designated 28 which is similar inits mounting and manner of movement to the actuating levers 28 whichactuate the type bars and the two previously mentioned special actuatinglevers-28 and '28".

In order that the step-by-step feeding movements imparted to the ratchetwheel 76 may be caused to occur only after each printing operation andfor each word spacing, a control mechanismfor the pawl 7 6 is employed,and in carrying out this part of my invention I utilize the so-c'alleduniversal bar commonly employed on typewriters, but with new functionsto be performed by it. This universal bar includes the arcshaped piece109, this member as customary lying in a slot on the rear of the slottedsegment 20 in position to be engaged and moved rearwardly by each typebar 18 as it is swung upwardly to printin position. From this pieceextend rearwarfly (Fig. 11) which are connected to the upstanding arms111 of a lever 112 (Figs. 1, 3 and 6) pivotally supported on the rearpart of frame 82, a spring '113 (Fig. 3) being attached to the lever tohold these parts in their forwardmost positions with the arcshapedmember 109 in the slot on the rear' side of the slotted segment 20. Theairrangement is such that on each actuation of any type bar thisuniversal bar is moved rearwardly as in ordinarywell known typewriters.I

One of the arms 110 is, in this instance, provided with a laterallyextending stud 114 (Fig. 11) which normally lies over a lug 115 on pawl76 the lug being shown in Figs. 6, 10 and 11. As longas the universalbar is in its forward or normal position and the stud overlies the lugon the pawl, the pawl is held out of engagement with the ratchet wheel76 and therefore regardless of the number of oscillations which thispawl may have by the rocking of shaft 55 the ratchet wheel is notactuated, but when the universal bar moves rearwardly as by theactuation of a type bar the stud rides past the lug 115 on the pawl andthis allows the pawl to move upwardly into engagement with the ratchetwheel so that the pawl .will on its nextrearward stroke turn the ratchetwheel one step. As the universal bar moves back or for wardly toward thefront of the machine to arms 110- its-normal position, the stud passesunder beneath a downwardland forward extension 116 of lever 112 (Figs. 1and 3), this actuating lever being adapted to be shifted by the actuator53 as before through the selection by the perforated record sheet or bythe manual depression of a special shift-key or bar as may be founddesirable, the key, if the same is utilized, being on a key lever suchas those previously described and'designatcd 11 and serving to movethisspecial actuating lever 28 forwardly so that its front end may beshifted downwardly by the actuator in precisely the same manner aspreviously described for the other actuating levers. As the rear end ofthis actuating lever 28' is elevated it engages the extension 116of'lever 112 and shifts the universal bar so as to release the lug 115of pawl 76 from the stud 114 in precisely the same way as the lug isreleased from the stud by the action of the different type bars.

The various parts and mechanism described above for automatically andpositively moving the carriage for word spacing, for tabulatingpurposes, and for the carriage return, are not claimed herein, but areclaimed in a companion application Serial No. 289,131, filed June 21,1928.

For elevating the platen so that the upper case letters of the type barswill be effective stroke of the actuator 53.

'for printing, the shifting mechanism ordiinto the path of movement ofthe actuator 53. It is not deemed-necessary, however, to

illustrate this special actuating lever as its operation will beunderstood by one skilled in the art.

The operation is as follows: The perforated record sheet which as.already stated is generally endless, is slipped over the sprockets 47and shield 43 by inserting the sheet over these parts through the slotor opening 46 in one of the sides of the frame.

The motor can then be started by closing a conveniently located switch,or the motor may previously havebeen in operation and may be caused tooperate the machine by throwing in a suitable clutch. The motor nowdriving shaft 56 swings the motor driven actuator 53 up and down andswings the oscillating members and 50. back and forth, these last twomentioned members swinging in unison, the forward motion being slightlyin advance of the downward Simultaneously with the forward stroke of theoscillating members 45 and 50 the pawl 49 by its engagement with theratchet 48, causes the sprockets and. therefore, the record sheet to bemoved forwardly one step. The unperforated portion of the record sheetholds the pins 37 at the rear ends of the actuating levers 28 out of thepath of movement of the rear oscillating member 45, but when aperforation comes beneath one of these pins the latter drops downwardlyin front of the oscillating member causing the actuating lever whichcarries the pinto be moved forwardly so that the front upward extensionthereof comes into the path of the downwardly moving actuator 53 whichrocks the actuating lever causing the corresponding type bar to be swungto printing position. In this way the different type bars are operatedautomatically, it being understood that during this automatic operationthekey levers 11 are not moved since they have no mechanical connectionwith the actuating levers. V

As each type bar swings to printing position the pawl 76 is permitted toengage the ratchet 76 and as the actuator swings upwardly the pawl movesrearwardly turning the nut 74 one step so as to positively space thecarriage one step and thereby position the platen for the next letter,it being understood that the pawl 76 is prevented from shifting theratchet and spacing the carriage except after a printing lmpression ismade and except for the word spacing, the pawl in the latter case beingreleased by the movement of the special actuating lever 28 which bringsabout the release of the pawl 76 the same as is done by a type bar. Thusand ratchet mechanism causing the carriage frame and carriage to bemoved laterally step bystep.

If atany time it is desired to insert matter not covered by the recordsheet such as the name, address, Salutation, and the like,

or a paragraph or more in the body of the matter being written, theoperator. disengages the pawl 49 so as to prevent the feed of the recordsheet. The matter thus referred to is inserted by the manual operationof the key levers, but as explained in the course of' the detaileddescription, the depression of the key levers does not direct- .thespacing both for the letters and for the words is done positivelythrough the pawl,

1y cause the 'type bars to be swungto printing position but on'the otherhand they are actuated as before by the motor driven aetuator 53, themanual depression of any particular key lever simply permitting thespring pin at the forward end of the corresponding actuating lever'to'beelevated in front of the forward oscillating bar 50 as indicated in Fig.7, whereupon the actuating lever is moved forwardly into the path of theactuator 53. Thatis to say, when the key is depressed, the forward motoractuated oscillating member 50 is rendered effective to shift theactuating lever 28 corresponding to that key into the path of theactuator 53 whereupon the actuating lever is rocked and thecorresponding type bar is swung to printing position without any furtherdownward movement on the part of the key or key lever since, as pointedout above, the latter has no mechanical connection with the typebar orwith the actuating lever associatedtherewith.

1 It, will be seen, therefore, that I have provided what may be trulystated to be an automatic typewriter as distinguished from theapplication of an'automatic operating mechanism to a typewriter.Heretofore these have been marketed in the form of two units, one thetypewriter andthe other the automatic operatinlg mechanism therefor. Bymy invention, provide the operating mechanism and typewriter in a'single'nnit with provision for automatically operating the type bars whollyindependent of and without. affecting the' keyboard, together with-means whereby. the machine can be manually operated, the effect of thedepression of the 'keys being. simply to trip the actuating levers or toshift them to a position to be engaged by the motor driven actuatoridentically as when; the machine is operated automatically, During thismanual operation the letter or word spacing is ac complished bypositively moving the carriage throughthe medium of the pawl 76 in thesame manner as when the selection occurs through the perforated recordsheet, the operator depressing the spacing key or bar to bring about theword spacing, this be operated by the actuator.

, I As explained above, the carriage is moved ,positively for letter andword spacing by the motor actuated pawl which gives the nut 74, andtherefore the carriage frame and Z carriage, a step-by-step movement.Additionally, as explained above, the indenting or tabulating and returnmovements are imparted to-the carriage frame and carriage, the nut74then being rotated continuously (as distinguishing from the step-by-stepmovement imparted by the pawl) through the motor driven shafts andgears, the engagement of the proper gear 86 or 87 with the gear 85 beingcaused by the motor driven actuator 53 and controlled either by theperforated record sheet or by the manual depression of the proper key,and the gears being disengaged automatically when the carriagereachesthe proper position predetermined in each instance by the position ofan'adjustable stop; I

The carriage can be moved by hand in either direction, if desired,whenthe pawl 76 is disengaged from the ratchet 76 (it .being normallydisengaged I as explained above). and to permit this it is onl necessaryto depress asmall lever 117 whic as shown in Fig. '1, is. supportedadjacent the ratchet wheel 76, this lever which is spring pressedholding in position a small detent 118 shown by dotted lines-in Fig; 6,and normally engaging the ratchet wheel 76. By depressng this lever asjust stated, the detent is released sufficiently from the ratchet wheelto permit the latter to turnfreely in either direction, thus permittingthe carriage frame and carriage to 'be moved by hand in eitherdirection.

While I'have shown one construction only which practice has demonstratedanswers the necessary requirements, it is obvious that the machine maybe modified in many of its details and I, therefore, do not desire to beconfined to the particular construction shown and described as theprinciple of the causingthe special actuating lever 28 to invention maybe carried out in other ways. I aim, therefore, in my.claims to coverall modifications which do not. involve a departure from the spirit andscope of my invention as set .forth in the appended claims.
